Calibration of the light-flavour jet mistagging efficiency of the b-tagging algorithms with Z+jets events using 139 $$\textrm{fb}^{-1}$$ of ATLAS proton–proton collision data at $$\sqrt{s} = 13$$ TeV
(Springer Nature, 2023-08)The identification of b-jets, referred to as b-tagging, is an important part of many physics analyses in the ATLAS experiment at the Large Hadron Collider and an accurate calibration of its performance is essential for ... -
Charged-hadron production in pp, p+Pb, Pb+Pb, and Xe+Xe collisions at √sNN = 5 TeV with the ATLAS detector at the LHC
(Springer, 2023-02-12)This paper presents measurements of charged-hadron spectra obtained in pp, p+Pb, and Pb+Pb collisions at s or sNN = 5.02 TeV, and in Xe+Xe collisions at sNN = 5.44 TeV. The data recorded by the ATLAS detector at the LHC ... -
Combination of inclusive top-quark pair production cross-section measurements using ATLAS and CMS data at s = 7 and 8 TeV
(Springer Nature, 2023-07-27)A combination of measurements of the inclusive top-quark pair production cross-section performed by ATLAS and CMS in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV at the LHC is presented. The cross-sections ... -
Combination of searches for Higgs boson pairs in pp collisions at root s=13 TeV with the ATLAS detector
(Elsevier, 2020-01-10)This letter presents a combination of searches for Higgs boson pair production using up to 36.1 of proton–proton collision data at a centre-of-mass energy TeV recorded with the ATLAS detector at the LHC. The combination ... -
Combined Measurement of the Higgs Boson Mass from the H→γγ and H→ZZ^{*}→4ℓ Decay Channels with the ATLAS Detector Using sqrt[s]=7, 8, and 13 TeV pp Collision Data.
(American Physical Society, 2023-12-22)A measurement of the mass of the Higgs boson combining the H→ZZ^{*}→4ℓ and H→γγ decay channels is presented. The result is based on 140 fb^{-1} of proton-proton collision data collected by the ATLAS detector during LHC ...
